Probably ... in a sense.

Current theory is that a planet was already mostly formed when a large planetoid collided and gave it a great glancing whack. This caused the Earth to spin as well as to shot out debris which coagulated to form the moon.

They are technically the same age as there is strong geophysical evidence that they were once part of the same body or rather that's part of the story.

It is estimated that the moon separated from the earth in a collision involving a 3rd body during the planets formation roughly the size of mars around 4.4 billion years ago.

So parts of the moon are from another body that formed near by.

The earth formed when a couple of asteroids and meteors colided in the middle of nowhere and formed earth. One of the parts of one of these asteroids was weaker and was knocked so that is was now the moon of this so-called planet. This means that this happened at the same time, so they are the same age, I think.

If the theory of impact formation is correct, the Earth is up to 100 to 200 million years older than the Moon, which was gouged out of the planet early in its formation by an impact with another planetary body. The Earth is about 4.6 billion years old (the same age as the other planets) and the Moon about 4.4 to 4.5 billion years old.
